Method for preparing plastic optical fiber preform

The present invention relates to a method for preparing a GI (graded index) plastic optical fiber preform having a radial refractive index gradient, the refractive index increasing gradually from the outer periphery of the preform toward the center thereof, comprising inserting a 1st plastic tube (i...

Zusammenfassung:	The present invention relates to a method for preparing a GI (graded index) plastic optical fiber preform having a radial refractive index gradient, the refractive index increasing gradually from the outer periphery of the preform toward the center thereof, comprising inserting a 1st plastic tube (inside diameter: d1i, outside diameter: d1o) ( 111 ) made of a first polymer (refractive index: n1) in a cylinder reactor (inside diameter: d0i, d1o=n2) into the 2nd plastic tube, injecting a precursor of a fourth polymer (refractive index: n'', n1
